TECHNICAL FIELD

The present disclosure relates to communications and, in particular, toan uplink control information transmission/configuration indicationmethod and device, a terminal and a base station.

BACKGROUND

In a communication system, user equipment (UE) needs to send necessaryuplink physical layer (L1) control information at a physical layer (L1)and uplink control information at a medium access control (MAC) layer(L2) to support uplink and downlink data transmission. In an example ofa long-term evolution/long-term evolution advance (LTE/LTE-A) system,the L1/L2 uplink control information (UCI) includes a scheduling request(SR), a hybrid automatic repeat request (HARQ) acknowledgement/negativeacknowledgement (ACK/NACK) and channel state information (CSI).

The SR is used for requesting uplink shared channel (UL-SCH) resourcesfrom an eNodeB;

The HARQ-ACK/NACK is used for HARQ acknowledge downlink data sent on adata channel, a physical downlink share channel (PDSCH).

The CSI includes a channel quality indication (CQI), a precoding matrixindicator/index (PMI), a rank indicator (RI), a channel stateinformation reference signal (CSI-RS) resource indicator/index resourceindicator/index (CRI) and the like, and is used for notifying an eNodeBof a downlink channel quality to help the eNodeB with downlinkscheduling.

The control information in the LTE is transmitted in two manners. If nouplink resource in a current subframe is allocated to UE for sendinguplink data, the UE sends the L1/L2 uplink control information in thephysical uplink control channel (PUCCH). If one or more uplink resourcesin the current subframe are allocated to the UE for sending the uplinkdata, the UE sends the L1/L2 uplink control information on part ofresources allocated to the physical shared control channel (PUSCH). Ifthe resources have been allocated to the UE for sending the uplink data,it is not necessary to send the SR. In the case of carrier aggregation(CA), the control information of multiple carriers may be aggregatedtogether for sending.

For control transmission on the PUCCH, there are several uplink controlchannel formats. As shown in Table 1, each format corresponds todifferent control information.

TABLE 1 Format Information 1 SR 1a 1-bit ACK/NACK with/without SR 1b2-bit ACK/NACK with/without SR 2 20-bit CSI 2 20-bit CSI + 1 or 2-bitACK/NACK (only for extended CP) 2a 20-bit CSI + 1-bit ACK/NACK (only fornormal CP) 2b 20-bit CSI + 2-bit ACK/NACK (only for normal CP) 3 ForFDD, up to 10-bit ACK/NACK; For frequency division duplex TDD, up to20-bit ACK/NACK 3 For FDD, up to 10-bit ACK/NACK + 1-bit SR; For TDD, upto 20-bit ACK/NACK + 1-bit SR

It can be seen from the above table that different types of controlinformation may be separately transmitted, or may be transmitted incombination with other types of control information, therebyrespectively forming different formats. The transmission of the sameformat in the same antenna configuration has a relatively fixed designand cannot be flexibly changed. The robustness of the transmittedcontent is the primary consideration in the LTE. A low error rate isrequired in transmission of the control information, because an error inthe control information may cause more serious consequences than anerror in data information. Therefore, the control information istransmitted in the most robust manner. The uplink control channelgenerally distinguishes different users through code division. The codedivision may adopt different orthogonal sequences or perform cyclicshift with the same sequence to achieve orthogonality.

The LTE/LTE-A is mainly intended for frequencies with relatively lowcommunication frequencies. At this time, the path loss in the system isnot large. But with the development and utilization of high frequencies,the communication frequency of the system is getting higher, and isgradually extended up to 4 GHz, 30 GHz and even 70 GHz. At this time,the path loss will significantly increase. In order to reduce the pathloss at the high frequency, beam transmission is used to acquirebeamforming gain so that coverage of the control channel can be ensured,which has become a trend. However, the beam transmission requiresreal-time accurate CSI. In the actual system, due to the blocking of thetransmission path and the movement of a terminal, the rotation of theterminal may affect the accuracy of the beam. In this case, therobustness of the control channel is challenged.

At present, if the uplink control information is transmitted in the mostrobust manner, the uplink control information is required to betransmitted in all beam directions, each direction needs to occupyresources, and the number of beams is generally twice the number ofantennas. In this case, a large amount of resources are required.Nevertheless, if the uplink control information is transmitted in themanner with the highest transmission efficiency, the robustness cannotbe guaranteed. In a word, the beam always lacks measurement accuracy andreal-time capability. Therefore, there is a lack of a transmissionmanner that guarantees both robustness and high transmission efficiencyat the same time during the transmission of the control information.

Therefore, both robustness and high transmission efficiency cannot beguaranteed at the same time during information transmissions.

In the first situation, which is the same as the data block,the ACK is fed back when the control information is received and decodedcorrectly; and the NACK is fed back when the control information isreceived but decoded incorrectly. In the second situation, the ACK isfed back only when the control information is received and decodedcorrectly; otherwise, nothing is fed back. In the third situation, theNACK is fed back only when the control information is received butdecoded incorrectly; otherwise, nothing is fed back.

The scheduling request message is mainly used for UE to initiate ascheduling request to the base station.

The CSI is a general term and includes various types of CSI, such asquantization information of a matrix of a channel, quantizationinformation of feature vectors of the channel, a channel qualityindicator/index (CQI), interference measurement, a precoding matrixindicator (PMI), a rank indicator (RI) of the channel, feedbackinformation of the number of precoding layers, a channel stateinformation reference signal resource indicator/index (CRI), portselection information, indication information of a measurement resourcelocation, and a beam indicator/index (BI).

Besides some traditional reported control information, the presentapplication further considers some new report information for improvingthe robustness and performance during the transmission. The new reportinformation mainly includes the sending manner switching requestinformation, receiving manner switching feedback information, and theindication information of information reporting mode described below.

The sending manner switching request information is mainly used by theterminal to request the base station to switch the sending manner, andthe sending manner includes a sending node, a sending beam, atransmission technology, a sending antenna, a sending sector, etc.

The receiving manner switching feedback information is mainly used bythe terminal to notify the base station to switch the receiving manner,and the receiving manner includes a receiving beam, a receiving antenna,a receiving sector, etc.

The indication information of information reporting mode is mainly usedfor indicating subsequent information reporting content.

Subsequent embodiments mainly describe how to use some more flexible andmore efficient transmission technologies to report some of aboveinformation.

Embodiment 4

In step 101, a first type of information is determined. The first typeof information includes: a response message, a scheduling requestmessage, channel state information (CSI), sending manner switchingrequest information, receiving manner switching feedback information,and indication information of information reporting mode, which arementioned above.

At each time instant, the terminal needs to determine the content ofinformation which needs to be reported according to a current feedbackmode, trigger signaling of the base station, and agreement between theterminal and the base station. At the same time instant, there may beonly one type of the first type of information which needs to bereported, or there may be multiple types of the first type ofinformation which need to be reported. When multiple types of the firsttype of information need to be reported, these types of the first typeof information may be combined and reported, or may be reportedseparately.

In step 102, a transmission configuration set corresponding to the firsttype of information is determined.

The first type of information may correspond to different transmissionconfiguration sets. The transmission configuration in the transmissionconfiguration set is used for transmitting the first type ofinformation. Specific parameter types included in the transmissionconfiguration will be described in the embodiments hereafter.

There are several manners for determining the transmission configurationset corresponding to the first type of information. Among them, onemanner is to achieve an agreement on the transmission configuration setcorresponding to the first type of information in advance; and anothermanner is to require configuration signaling of the base station toconfigure the transmission configuration set. If the base station hassent configuration set indication signaling, the terminal needs todetermine the transmission configuration set according to theconfiguration set indication signaling. Different terminals mayconfigure different transmission configuration sets. Since differentuplink or downlink transmission modes may correspond to differentagreements or configurations of the transmission configuration set,regardless of the manner of agreement in advance or the manner requiringthe indication of the signaling of the base station, the terminal needsto determine the transmission configuration set in conjunction with theuplink or downlink transmission mode. Since information types includedin different first type of information may correspond to agreements orconfigurations of different transmission configuration sets, regardlessof the manner of agreement in advance or the manner requiring theindication of the signaling of the base station, the terminal needs todetermine the transmission configuration set in conjunction with theinformation type included in the first type of information.

It is to be noted that when the first type of information is theresponse message, response messages directed to different respondedobjects should be considered as different types. For example, theresponse message for data and the response message for control maycorrespond to different transmission configuration sets.

It is to be noted that when the first type of information is the CSI,different sub-types of the CSI should be considered as different types.For example, the CRI, the RI, the PMI and the CQI may correspond todifferent transmission configuration sets.

For the response message, the transmission configuration set for thecase where the responded object is first transmitted data may bedifferent from the transmission configuration set for the case where theresponded object is retransmitted data. Therefore, regardless of themanner of agreement in advance or the manner requiring the indication ofthe signaling of the base station, the terminal needs to determine thetransmission configuration set in conjunction of whether the data, towhich the response message is responsive, is first transmitted orretransmitted, as well as how many times the data has beenretransmitted.

The better different transmission configuration sets may be different,so that different sets may be determined in advance according tofeatures of various types of the first type of information. In general,extreme importance and information of low sending frequency may take atransmission configuration with high robustness; and information ofordinary importance may take a transmission configuration withrelatively high robustness and a transmission configuration withrelatively high transmission efficiency. It is to be noted that higherthe robustness is, more resources are required for transmittinginformation. The resources include time domain resources, frequencydomain resources, spatial domain resources, a code domain resources andpower. The high transmission efficiency means that the information istransmitted successfully by using fewer resources.

In step 103, a transmission configuration is selected from thetransmission configuration set.

If the base station has sent configuration selection indicationsignaling, the terminal needs to select the transmission configurationin the transmission configuration set according to the configurationselection indication signaling. The signaling may be physical layercontrol signaling, which allows to quickly switch between configurationsand to flexibly select the transmission configuration in thetransmission configuration set. There is another situation where thereis no indication signaling. In this situation, the terminal mayautonomously and flexibly select the transmission configuration.Different terminals may select different transmission configurations inthe transmission configuration set. Alternatively, the terminal mayselect the transmission configuration according to the transmissionmode, the information type included in the first type of information,the responded object and retransmission times of response information.Different transmission configurations in the transmission configurationset may be selected for different uplink or downlink transmission modes.Different transmission configurations in the transmission configurationset may be selected for different information types included in thefirst type of information.

It is to be noted that when the first type of information is theresponse message, response messages directed to different respondedobjects should be considered as different types. For example, theresponse message for data and the response message for the control maycorrespond to different transmission configuration selection.

It is to be noted that when the first type of information is the CSI,different sub-types of the CSI should be considered as different types.For example, the CRI, the RI, the PMI and the CQI may correspond todifferent transmission configuration selection.

For the response message, the transmission configuration selected forthe case where the responded object is first transmitted data may bedifferent from the transmission configuration selected for the casewhere the responded object is retransmitted data. Therefore, regardlessof the manner of agreement in advance or the manner requiring theindication of the signaling of the base station, the terminal needs todetermine the transmission configuration selection in conjunction ofwhether the responded data is first transmitted or retransmitted, aswell as how many times the data has been retransmitted. If thecorresponding transmission configuration set includes only onetransmission configuration, this transmission configuration is directlyused.

In step 104, the first type of information is transmitted according tothe selected transmission configuration.

Embodiment 5

The terminal determines the transmission configuration set according tothe information type included in the first type of information. Specifictransmission configuration types are described in the subsequentembodiments. For specific manner for determining this set in thisembodiment, reference may be made to the manner described in theembodiment 1.

There is one situation that one type of the first type of informationcorresponds to one transmission configuration set, as shown in Table 2.

TABLE 2 Scheduling request message Transmission configuration 11,transmission configuration 12 Response message of the controlTransmission configuration 21, information transmission configuration 22Response message of the data Transmission configuration 31, informationtransmission configuration 32 Sending manner switching Transmissionconfiguration 41, request information transmission configuration 42Receiving manner switching Transmission configuration 51, feedbackinformation transmission configuration 52 Indication information ofTransmission configuration 61, information reporting mode transmissionconfiguration 62

The situation that one type of the first type of information correspondsto multiple configurations is listed herein. In one example, one type ofthe first type of information may correspond to only one configuration.In another example, part of the type of the first type of informationcorresponds to only one configuration, and part of the type of the firsttype of information corresponds to multiple configurations.

There is another situation that each of groups into which the first typeof information is grouped corresponds to one transmission configurationset. There are several manners for grouping the transmissionconfiguration sets.

The first preferable grouping manner is that a first group includes atleast one of the scheduling request message, the response message, theBI, the CRI, the RI, the sending manner switching request information,the receiving manner switching feedback information, or the indicationinformation of information reporting mode, and a second group includesat least one of: the CQI or the PMI, as shown in Table 3.

TABLE 3 Group 1 of the At least one of the response message, the BI, thefirst type of CRI, the RI, the sending manner switching requestinformation information, the receiving manner switching feedbackinformation, or the indication information of information reporting modeGroup 2 of the At least one of the CQI or the PMI first type ofinformation

If there is the feedback of multiple PMIs including a long period, afirst PMI fed back by a broadband, a short period and a second PMI fedback by a sub-band, the grouping manner at this time is as shown inTable 4.

TABLE 4 Group 1 of the At least one of the response message, the BI, thefirst type of CRI, the RI, the sending manner switching requestinformation information, the receiving manner switching feedbackinformation, the indication information of information reporting mode,or the first PMI Group 2 of the At least one of the CQI or a second PMIfirst type of information

The second preferable grouping manner is that the first group includesat least one of the scheduling request message, the response message,the sending manner switching request information, the receiving mannerswitching feedback information, or the indication information ofinformation reporting mode, and the second group includes at least oneof pieces of the CSI, as shown in Table 5.

TABLE 5 Group 1 of the At least one of the scheduling request message,the first type of response message, the sending manner switchinginformation request information, the receiving manner switching feedbackinformation, or the indication information of information reporting modeGroup 2 of the At least one of pieces of the CSI first type ofinformation

The third preferable grouping manner is that the first group includes atleast one of the scheduling request message, the sending mannerswitching request information, the receiving manner switching feedbackinformation, or the indication information of information reportingmode, and the second group includes at least one of the response messageor the CSI, as shown in Table 6.

TABLE 6 Group 1 of the The scheduling request message, the sendingmanner first type of switching request information, the receiving mannerinformation switching feedback information, and the indicationinformation of information reporting mode Group 2 of the The responsemessage, and the CSI first type of information

In addition the two grouping manners described above, a manner forgrouping more groups may also be easily extended. Some information withsimilar importance and sending frequency may be grouped into one group.Each group may correspond to one transmission configuration set.

One transmission configuration includes one or more set of transmissionconfigurations. Different groups may correspond to differenttransmission configuration sets due to its different characteristics.

Embodiment 6

This embodiment is mainly used for describe some configuration typesincluded in the transmission configuration. These configuration typesmainly include:

at least one configuration of numerology.

In a general OFDM-based wireless communication system, basictransmission parameters mainly include following classifications: a timedomain symbol length, the number of subcarriers, a subcarrier spacing, afrequency domain guard band, a cyclic prefix (CP), a time domain guardperiod (GP), and the number of points in fast Fourier transform (FFT)algorithm.

The time domain signal length refers to an OFDM symbol length.Modulation symbols are carried on M OFDM subcarriers. Modulation symbolsare carried on M OFDM subcarriers, these subcarriers constitute a timedomain sample point after transformed to the time domain, and the timedomain sample point and the guard period form a time domain OFDM symbol.Generally speaking, the OFDM symbol length is related to the number andspacing of subcarriers in the frequency domain. That is, with the samebandwidth, the larger the number of subcarriers is and the smaller thesubcarrier spacing is, the longer the OFDM symbol length is, which maybe described as that with the same subcarrier spacing, the larger thenumber of subcarriers is, the longer the OFDM symbol length is, and viceversa.

The number of subcarriers refers to the number of subcarriers carryingthe modulation symbols in the frequency domain corresponding to the sameone OFDM symbol.

The subcarrier spacing refers to the spacing of center frequenciesbetween the subcarriers. Generally speaking, in order or maintainorthogonality, the smaller the subcarrier spacing is, the higherrequirements of required waveform are, and the longer a window in thetime domain is, so that the longer the time domain symbol length is, andvice versa.

The frequency domain guard band refers to that some bandwidths on bothsides are generally reserved as guard bands during the informationtransmission. For example, in the current LTE system with 20 MHzbandwidth, actually only 100 resource blocks (RBs) are used, and only1200 subcarriers, that is, total 18 MHz bandwidth, are occupied, whichmeans that 2 MHz guard bands are reserved. The guard bands are generallyon both sides of the bandwidth and mainly used for avoiding impact ofout-of-band emission on performance when other wireless communicationsystems send information.

The CP generally refers to some prefixes added in the front of some timedomain sample points formed after the frequency domain signals aretransformed into the time domain. The prefixes generally are copies oflatter part of sample points of a string of time domain sample points.For example, a series of signals 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 towhich a cyclic prefix with a length of 4 is added are signals 6, 7, 8,9, 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

For the time domain guard period (GP), during radio frequency (RF)precoding, switching from one precoding to another precoding requirescertain processing time, so that similar guard periods are alsorequired. Although some other places also have similar concepts of theguard period, various guard periods in the present application are allconsidered as one type of basic transmission parameters.

The number of points in fast Fourier transform (FFT) algorithm isgenerally related to the number of subcarriers and the bandwidth, but isnot completely equal to the number of active subcarriers. For example,for a 20 MHz/10 MHz LTE system, in 2048 points and 1024 points areadopted respectively, the number of active subcarriers is just 1200 and600 respectively.
